The filters in Table 6 must be wired to the DC output of

the drive, as close to the drive as possible. The ground

connection from the filter must be wired to solid earth

ground (resistance less than 500 ohms); not machine

ground. This is very important!

The end user must use the filtering listed in Exhibit A to

comply with CE. The OEM may choose to provide

alternative filtering that encompasses the Reliance Electric

drive and other electronics within the same panel.

The OEM has this liberty because CE is a machinery

directive. Whether or not every component in the OEM’s

machinery meets CE, the OEM must still submit his

machine for CE approval. Thus, no component must

necessarily meet CE within the machine, as long as the

OEM takes the necessary steps to guarantee the machine

does meet CE. By the same token, even if every

component in the OEM’s machine does meet CE, the

machine will not necessarily meet CE as a machine.

Use of CE-approved wiring practices, such as proper

shielding, and the filters listed in Exhibit A guarantee the

drive will meet EN55011 (1991 emissions standard) and

EN50082-1 (1992 immunity standard).
